I think in the rain you have to calculate the Relative Air index. Kinda the reverse of my question. [img]images/icons/rolleyes.gif[/img] Big drops or small? [img]images/icons/grin.gif[/img]

On a more serious note I've heard from some folks that rain doesn't affect accuracy...a hypothesis I find vastly amusing. I've read two articles on the subject that were based on both simulated and actual rain. In the Sim. evaluation which had fall rates on the order of 1"/hour it increased dispersion on the order of 3-5 times with a 7mm bullet as I recall. The actual rain test was with light showers to drizzle and and had no measurable influence at 100 yards.
